Chapter 1: The internal environment and homeostasis of the human body.
1. Body fluids: body.

Anonymous users2024-02-051.According to the relationship between the components of body fluids, the water of plasma comes from tissue fluid, lymph, intracellular fluid, and water absorbed by the digestive tract.
2.The red blood cells in the capillaries cannot reach the interstitial fluid. So it's 0 layers of film.
3.The above experiment is to detect the presence of protein, if it will appear purple, indicating that there is protein in the diluted mucus, and protein is a macromolecular substance. Generally, the amount of dilute mucus is very small, if it indicates that capillary permeability is enhanced, so the patient may suffer from allergic rhinitis.
4.Considering how O2 and CO2 enter the body and are excreted from the body, their entry or excretion is the diffusion from high concentration to low concentration, so the concentration relationship of O2 is that plasma is greater than tissue fluid and intracellular fluid. CO2 is that plasma is less than tissue fluid and less intracellular fluid.
5 .6 layers of film. Oxygen reaches the histiocytes and is utilized through 1 layer of erythrocyte membrane, 1 layer of capillary wall cell membrane, 1 layer of tissue cell membrane, and 2 layers of membrane entering the mitochondria, ** The stroma of the chondrial matrix is utilized, a total of 6 membranes.

3. Purple, there is protein, allergic reaction produces antibodies, the composition of the antibody is globulin 4, the transmembrane transport of gas is free diffusion, along the concentration gradient.
Oxygen: plasma, interstitial fluid, intracellular fluid.
Carbon dioxide: plasma, interstitial fluid, intracellular fluid.
5. One layer of red blood cell membrane + two layers of capillary wall membrane + one layer of tissue cell membrane + two layers of mitochondrial membrane = 6 at least six layers of Mo.

Anonymous users2024-02-031'Digestive tract, lymphatic vessels, interstitial fluid 2, red blood cells do not enter the interstitial fluid, if you want to enter the 2 layers of membrane, because one layer goes in and one layer out 4 Oxygen concentration: plasma >> interstitial fluid Carbon dioxide: the order is reversed Reason:
Free diffusion 5, at least four membranes Two layers of blood vessels, one layer of cell membranes, one layer of mitochondria (at least) (and utilized).

Anonymous users2024-02-02Question 5 should be 5 layers, but it only enters the mitochondria, not the mitochondria, so it is only counted as one layer.

Dizzy, buy a reference book.

First, the dominant recessive nature of albinism and sickle anemia was determined, and according to the left half of Figure 1, it can be concluded that anemia is a recessive genetic disease, which is bb; Then look at Figure 2, because if it is normal, it can be cut, and if it is not normal, it can't, so B is normal, C is albino, and both are homozygous, only A is heterozygous (because A can cut out three pieces: DNA is a double helix structure, only one of A can be cut, B can be cut all of them, cut into two short and two long, C is not cut) Because albinism is a recessive genetic disease, it is AA, so it can be known that B is AA and C is AA >>>More
