Cardiovascular

Primary organ of the circulatory system and describe as Hollow muscular organ that circulates around the body

Heart

outer layer of the heart

Epicardium 

middle and thickest layer of the heart

Myocardium 

Inner layer of the heart

endocardium 

smallest cardiac chamber

Right atrium

second largest cardiac chamber

Right ventricle

third largest cardiac chamber

Left atrium

largest cardiac chamber

Left ventricle

right atrioventricular valve

Tricuspid valve

left atrioventricular valve

mitral valve

situated between the right ventricle and pulmonary artery

Pulmonic valve

situated between left ventricle and aorta

Aortic valve

Transport oxygenated blood and nutrients to myocardia layer of the heart

Coronary arteries

cord/string-like structure

Chordae tandinea

connected to the ventricular walls

Papillary muscles

connected inside the right atrium

Vena cava

connected to the right ventricle inside

Pulmonary artery

connected to the left atrium inside

Pulmonary vein

connected to the left ventricle inside

Aorta

Conducting tubes that transport blood throughout the body

Blood vessels

Arteries and arterioles generally transports oxygenated blood except?

1) Pulmonary artery

2) Umbilical artery

3) Omphalomesenteric artery

4) Vitelline artery

transports deoxygenated blood towards/back to the heart. It has valves inside that prevent the backflow of blood.

Veins and venules

Veins and venules generally transports deoxygenated blood except:

1) Pulmonary vein

2) Umbilical vein

3) Omphalomesenteric vein

4) Vitelline vein

small/microscopic vessels and site of exchange of oxygen, nutrients, and waste products between tissues and circulation

Capillaries

Layers of blood vessels that is Made up of endothelium or endothelial cells

Tunica intima

Layers of blood vessels that is made up of smooth muscles and thickest in arteries

Tunica media

Layers of blood vessels that is made up of connective tissue

Tunica adventitia

transports oxygen molecule due to hemoglobin

Red blood cells/erythrocytes 

It like a soldiers of the body and fights the infections

White blood cells/leukocytes 

Two types of white blood cells/leukocytes 

Granulocytes and agranulocyte

It’s a type of granulocytes and it increases when there’s bacterial infection occurs

Neutrophils

It’s a type of granulocytes increases when there’s parasitic infection

Eosinophils 

It’s a type of granulocytes and it increases when there’s allergic reaction

Basophils 

The cytoplasmic granules is absent while nucleus is present at the center

Agranulocyte

undifferentiated lymphocytes that were transported into the thymus

T cell 

Undifferentiated lymphocytes that were transported into the bursa of fabricius (avians) or bone marrow (mammals)

B cell 

5 types of immunoglobulins:

Ig-M,Ig-G,Ig-A,gI-E,gI-D

it can be differentiated from lymphocytes by the presence of indented nucleus (heart shaped/v shaped)

Monocytes 

remnants/fragments of bone marrow megakaryocytes

platelets/thrombocytes

contains clotting factor

Plasma

doesn’t contain any clotting factor

Serum
