Clotting time is a general term for the time required for a sample of blood to form a clot, or, in medical terms, coagulate. The term "clotting time" is often used when referring to tests such as the prothrombin time (PT) , activated partial thromboplastin time (aPTT or PTT), activated clotting time (ACT), thrombin time (TT), or Reptilase time .
In renal physiology, renal blood flow (RBF) is the volume of blood delivered to the kidneys per unit time. In humans, the kidneys together receive roughly 20 - 25% of cardiac output, amounting to 1.2 - 1.3 L/min in a healthy adult. [1] It passes about 94% to the cortex.
A healthy human has 12 to 20 grams of hemoglobin in every 100 mL of blood. Hemoglobin is a metalloprotein, a chromoprotein, and globulin. In mammals, hemoglobin makes up about 96% of a red blood cell's dry weight (excluding water), and around 35% of the total weight (including water). [5]
Physiology of blood coagulation is based on hemostasis, the normal bodily process that stops bleeding. Coagulation is a part of an integrated series of haemostatic reactions, involving plasma, platelet, and vascular components. [13] Hemostasis consists of four main stages:
7.8-20 × 10 −4: Arginine: Amino acid 6-17 × 10 −6: 1.3-3.6 × 10 −5: Arsenic: normal range 2-62 × 10 −9: chronic poisoning 100-500 × 10 −9: acute poisoning 600-9300 × 10 −9: Ascorbic acid (Vitamin C) Important vitamin 1-15 × 10 −6: 6-20 × 10 −6: Aspartic acid: Amino acid 0-3 × 10 −6: In WBCs 2.5-4.0 × 10 −4: 9-12 × ...
A:Normal red blood cells are shown flowing freely in a blood vessel on the top of the diagram. The inset image shows a cross-section of a normal red blood cell with normal hemoglobin. B:Demonstrates abnormal, sickled red blood cells blocking blood flow in a blood vessel (vaso-occlusive crisis). The inset image shows a cross-section of a sickle ...

Hemostasis occurs when blood is present outside of the body or blood vessels. It is the innate response for the body to stop bleeding and loss of blood. During hemostasis three steps occur in a rapid sequence. Vascular spasm is the first response as the blood vessels constrict to allow less blood to be lost.
