What are the things that are typically contained in blood?

Let's talk about the blood itself, blood is composed of plasma and blood cells, plasma is water, albumin, globulin, fibrinogen, and related to the body's immunity, the stability of the internal environment, the transportation of various nutrients, and blood coagulation. Blood cells include white blood cells, red blood cells and platelets, and white blood cells are divided into mesogranulocytes, eosinophils, basophils, monocytes and lymphocytes. These cells are associated with inflammation and anti-inflammatory responses, cleansing of the internal environment, acid-base balance, allergic reactions, and physiological activities such as gas transport and exchange, blood color, coagulation, etc.

In addition, the blood contains potassium, sodium, hydrogen. Chlorine and other ions related to acid-base balance and cell electrophysiology, calcium, magnesium, iron, zinc and other essential trace elements for the body, as well as sugar, fatty acids and other energy substances ingested from food, in addition to some water-soluble or fat-soluble vitamins that are indirectly absorbed into the blood, play an important role in the body's **, blood production, trace element absorption, cardiovascular and cerebrovascular health, etc., endocrine gland secretion hormones, such as insulin, glucagon, glucocorticoids, etc. are also in the blood, Regulates the functional activities and metabolism of various tissues in the body, and maintains the stability of the internal environment.

These are my personal summaries, I hope it will be useful to you!

Blood is an opaque red fluid that flows through the heart and blood vessels, and its main components are plasma and blood cells. It belongs to connective tissue, that is, the structural hierarchy in the living system. Blood contains a variety of nutrients, such as inorganic salts, oxygen, as well as cell metabolites, hormones, enzymes and antibodies, etc., which have the role of nourishing tissues, regulating organ activities and defending against harmful substances.

Physiological and pathological changes in various organs of the human body often cause changes in blood composition, so it is often necessary to diagnose diseases through blood tests after illness.

Components of the blood:

Blood is made up of formed components and plasma. There are three types of formed components (blood cells) that make up 45% of the blood.

1.Red blood cells are the most abundant of the formed components of blood, they are small, round and flat, with thick edges, concave in the middle, without seeds, and their main component is hemoglobin. The main characteristic of hemoglobin is that it is easy to combine with oxygen in places with a lot of oxygen, and it is easy to separate from oxygen in places with less oxygen.

Therefore, its main function is to transport oxygen. Hemoglobin is red, and the degree of combination with oxygen determines its color, arterial blood with more oxygen is bright red, and venous blood with less oxygen is dark red.

2.White blood cells:

Leukocytes are colorless, nucleated round cells, slightly larger than red blood cells, the normal value of leukocytes is that there are --- types of leukocytes per liter of blood, such as granulosa cells, lymphocytes, etc., they each occupy a certain proportion in the blood, when they are sick, they will change, and can be used as reference data for diagnosing diseases.

3.Platelets:

Platelets are small, nucleated bodies whose main function is to promote blood clotting. There are --- platelets per liter of blood, and when the number is reduced to a certain level, it is easy to bleed in **, mucous membranes, internal organs, etc.

Except for the formed components, the other parts of the blood are plasma. Plasma is a liquid component of the blood. Plasma contains many important substances, including proteins, inorganic salts (potassium, sodium, calcium, etc.), antibodies, hormones, etc. Among them, moisture accounts for 91%-92%.

For details, it is recommended to consult the doctor of Wuhan Modern Obstetrics and Gynecology in Qiaokou.

Blood contains many components and nutrients, such as albumin, which is extracted from the blood.

Blood is the fluid that circulates and flows in the blood vessels of the human body, and blood is made up of two parts, one is blood cells and the other is plasma. Blood cells are made up of three types of cells, namely red blood cells, white blood cells and platelets, which have different amounts in the blood and perform different physiological functions. For example, the main function of red blood cells is to transport oxygen and carbon dioxide, the main function of platelets is to stop bleeding, and the function of white blood cells is to maintain the normal immune function of the body.

When the number of platelets, white blood cells, or red blood cells is abnormal, the physiological functions of the human body will change significantly. Plasma is mainly composed of water, various inorganic ions, various proteins and antibodies, water accounts for more than 99% of plasma, including potassium ions, chloride ions, albumin, globulins and various coagulation factors, which are the components of blood.

Human blood is made up of 55-60% plasma and 40-45% blood cells (red blood cells, white blood cells, platelets). Blood cells are mainly red blood cells, which carry oxygen to all parts of the body and send the carbon dioxide produced by metabolism to the lungs and excrete it with exhalation. The second is white blood cells, which can help the human body resist the invasion of bacteria, viruses and other foreign substances, and are the guardians of human health; Then there are platelets.

Composition of Blood Blood is a fluid tissue that exists within the cardiovascular system, and it consists of two parts: cellular and fluid. The cellular part refers to the forming part of the blood, collectively known as blood cells. The liquid part is called plasma.

The total amount of blood in the human body accounts for about 7-8% of body weight, and under normal circumstances, there is more blood per kilogram of body weight in men than in women, and in young children than in adults.

1. Plasma. Plasma is the liquid component of blood, accounting for about 50-60% of the whole blood cellar, in addition to water, plasma also contains various plasma proteins, inorganic salts, glucose, hormones and other substances. Plasma has a variety of functions such as maintaining osmotic pressure, maintaining normal blood pH, defense, and fluid regulation.

2. Blood cells. Hemoparhorax is divided into red blood cells, white blood cells, and platelets. (1) Red blood cells.

Also known as red blood cells, they are the most abundant type of blood cells. The number of red blood cells in a normal adult male is 4.5 million cubic centimeters, with an average of 5 million; Adult women are 3.8 million to 4.6 million cubic centimeters, with an average of 4.2 million. The main function of red blood cells is to transport oxygen and carbon dioxide and buffer changes in blood pH.

Red blood cells contain an important protein called hemoglobin, and the main function of red blood cells is done by hemoglobin. Normal adult men have 12-15 grams of hemoglobin per 100 milliliters of blood and 11-14 grams of women, and hemoglobin is closely related to the number of red blood cells. A lower than normal number of red blood cells or hemoglobin is called anemia.

2) White blood cells. White blood cells are colorless and larger in size than red blood cells. The number of white blood cells in the blood of normal people is 5000-9000 per cubic centimeter when they are at rest, and their physiological changes range are large, such as after eating, inflammation, menstrual period, etc., which can cause changes in the number of white blood cells.

Leukocytes are further divided into granular neutrophils, eosinophils, basophils, granular lymphomacytes, and monocytes. The main functions of white blood cells are to defend against germs, immune, and remove dead tissue. (3) Platelets.

Platelets are seedless, also known as thrombocytes. The platelet content of a normal person is 10-300,000 cubic centimeters, and the number of platelets varies greatly with different functional states. The main functions of platelets include promoting hemostasis and accelerating blood clotting, as well as nutritional and supportive effects.

Plasma, blood cells (white blood cells, red blood cells, platelets).

Red blood cells, white blood cells, platelets, plasma...

Blood members are divided into two categories: those that are visible under a microscope and are called "formed components," which mainly include red blood cells, white blood cells, and platelets, and these three types of cells are collectively called blood cells. The second group is the invisible members, called the "invisible components" of plasma, which are non-cellular components.

Plasma includes various minerals such as sodium, potassium, calcium, magnesium, copper, etc.; energy substances, such as glucose, lactose, etc.; lipids, such as cholesterol, phospholipids, triglycerides, etc.; hormones, such as insulin, thyroxine, etc.; Protein-like substances, such as albumin, globulin, etc.; In addition, there are various enzymes, vitamins, and small amounts of oxygen and carbon dioxide. Under the microscope, the blood cells in the blood are not as dense as they can be seen with the naked eye, and the yellowish plasma becomes the background color of our vision.

Hello dear!

Blood is mainly made up of red blood cells, white blood cells, platelets, and blood fluid.

Red blood cells (also known as red blood cells) are spherical cells made up of protein molecules carried by iron ions surrounded by red cell membranes, whose primary function is to transport oxygen to tissues and cells in the body.

White blood cells (also known as white blood cells) are the main cells that fight infection, and they are able to attack and kill pathogens, protecting the body from disease.

Platelets (also known as blood clots) are round or oval-shaped cells whose main function is to promote blood clotting and prevent bleeding.

Blood fluid (also known as plasma) is the most important part of blood, it is the suspension of cells in the blood, and the main components are water, electrolytes, proteins, sugars, hormones, vitamins and other similar substances.

I hope mine can help you!
