About our Blood

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

Function is for oxygen transport

Do not have nucleii; have double concave shape

It is produced in the red bone marrow

Thrombocytes: large cells in the bone marrow

Helps wounds heal

Help blood clots to slow or stop bleeding

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

Smaller than Red Blood Cells

Where tissue is injured, platelets, plasma proteins, and calcium ions react to from fibrin, which trap RBC to form a clot

Blood transports fats, proteins and carbohydrates

Transports Oxygen and Carbon dioxide between lungs and body tissues.

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

Heals injured tissue and preserves some alkalinity in body tissues.

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

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

Plasma contains fibrinogen which prevents blood clots.

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

These cells are also called leukocytes

Their purpose is to fight infection.

They are produced in the bone marrow

There are 5 categories of white blood cells

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

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

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

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).

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