Soft tissue organs in the body repair injury through a multi-step process that begins as platelets from torn vessels work to form a mesh-like clot that prevents blood loss. Inflammation in the area occurs as tissue repair begins in the damaged area. Mast cells release histamine that dilates blood vessels and increases blood flow to…

Female sex cells

The ovaries produce secondary oocytes -the female sex cells. During fetal development stem cells, called oogonia, go through mitosis. Some of these cells develop into 46-chromosome primary oocytes. At the onset of female puberty tens of thousands of primary oocytes each form part of a primordial follicle in the ovaries. Between menarche and menopause, each…

Involuntary reflexes

Cardiac output

With each contraction of the ventricles blood is pumped out of the heart. Stroke volume is the amount of blood a ventricle pumps out in one contraction. Cardiac output is the volume of blood that each ventricle ejects every minute. To find the cardiac output volume, multiply the number of heart beats in one minute…
