About our Blood

White blood cells (sophia)

Monocyte (Agranulocytes): fights off bacteria, viruses and fungi. One of the biggest type of WBC in immune system. Develop into macrophages in the tissue

Basophil (Granulocytes): Release histamine (causes smooth muscle contraction and dilation of capillaries) and other mediators for inflammation. They have heparin, an anticoagulant (which prevents the blood from becoming a semi-solid).

Lymphocyte (Agranulocytes): function to eliminate the antigen by releasing antibodies or signaling other cells of the immune system

Lymphocyte

Eosinophils (Granulocytes): They kill parasitic worms. Their efforts are important with asthma and allergies.

Neutrophils (Granulocytes): They Phagocytize bacteria (ingest bacteria).

There are 5 categories of white blood cells

They are produced in the bone marrow

Their purpose is to fight infection.

These cells are also called leukocytes

Plasma

Plasma: is 92% water with various salts and proteins.

Plasma contains fibrinogen which prevents blood clots.

Transports antibodies to fight infections (in various parts of body).

Is supposed to transport nutrients wastes, water and carbon dioxide.

Why do we have it?

Heals injured tissue and preserves some alkalinity in body tissues.

can carry communication molecules, fight infection and maintain water balance with kidneys.

Transports Oxygen and Carbon dioxide between lungs and body tissues.

Blood transports fats, proteins and carbohydrates

Platelets

Functions in blood clotting, which prevents excess bleeding when a blood vessel is injured

Thrombocytes: large cells in the bone marrow

Help blood clots to slow or stop bleeding

Thrombocytes

Helps wounds heal

Red Blood Cells

It is produced in the red bone marrow

Do not have nucleii; have double concave shape

Function is for oxygen transport

Erythrocytes: contain a pigment of hemoglobin and helps transport oxygen and carbon dioxide to and from tissues
