Clotting factors that are required for exogenous coagulation and not required for endogenous coagula

Coagulation factors are the initiation of the endogenous coagulation system and are not involved in the exogenous coagulation process.

Differences: 1. Initiation factor. Endogenous coagulation: activating factors such as collagen fibers; Exogenous coagulation: tissue damage production factor.

2. Participate in the reaction step. endogenous coagulation: more; Exogenous coagulation: Rare.

3. Produce blood clotting velocity. endogenous coagulation: slower; Exogenous coagulation: Rapid.

Similarities: Both exogenous and endogenous coagulation systems are components of the coagulation system and play an irreplaceable role in the coagulation process.

The coagulation factors involved in the endogenous coagulation system are xii, xi, ix, viii;

The coagulation factors involved in the exogenous coagulation system are VII and III;

The coagulation factors involved in the common coagulation pathway are X, V, II, I, and IV.

There are three ways for human and alternate bodies to coagulate.

1. Endogenous coagulation pathway: from factor activation to activation of factor X after the formation of A-PF3Ca2+ complex;

2. Exogenous coagulation pathway: from the activation of factors to the formation of A-Ca2+-TF activating factors;

3. Common coagulation pathway: from the activation of factor X to the formation of fibrin, it is the common coagulation pathway of endogenous and exogenous coagulation.

The factor required for exogenous coagulation and intrinsic coagulation for cave blood is ()aFactor Bfactor

c.Factor spring withering.

d.Factor Correct Answer: B

Answer]: A blood coagulation is the process of changing the blood from a flowing state to a non-flowing gelatinous blood coagulation bridge, which can be divided into endogenous coagulation pathway and exogenous coagulation pathway according to the different pathways of activating factor X.

Answer]: A Analysis: The exogenous coagulation pathway refers to the coagulation process initiated by the exposure of tissue factors (i.e., F) when blood vessels are damaged.

The intrinsic coagulation pathway refers to the coagulation process in which F binds to the surface of a foreign body and initiates excavation. Lead Caidi factor is a co-activator of both endogenous and exogenous coagulation pathways. Thrombin formation is the second stage of the process of coagulation and induced nuclear blood.

Platelet factor factor is one of the phospholipid components of platelet membrane and is an important factor for platelets to participate in the coagulation process. Master the knowledge of "blood cells and their functions and blood coagulation, anticoagulation and fibrinolysis".

Answer]: cThis question examines the pharmacological effects and mechanism of direct oral anticoagulant repellent. The intersection of exogenous and endogenous coagulation pathways is coagulation due to clear sizin xa. Therefore, the correct answer is answer c.

a.Because of the search for the reputation of the Son of God I

b.Factor III

c.Factor VII

d.Because of the loss of the son xii

Correct answer: d

Answer: C

The initiating factor of the extrinsic coagulation pathway--factor, the initiating factor of the ascending coagulation pathway of the inner finch -- the initiation factor of the initiation belt. Therefore, C.
