, also known as the circulatory system, is a complex network that consists of the heart, blood vessels, and blood. Its primary function is to transport nutrients, oxygen, hormones, and waste throughout the body.

cardiovascular system

helps in maintaining homeostasis, regulating blood pressure, and facilitating immune responses. It ensures that tissues receive adequate blood supply to meet metabolic demands and helps remove waste products from the body.

cardiovascular system

The cardiovascular system includes

Heart Blood vessels Blood

: A muscular organ that pumps blood through the circulatory system

Heart

: These include arteries (which carry blood away from the heart), veins (which return blood to the heart), and capillaries (small vessels where the exchange of substances occurs).

Blood Vessels

: The fluid that carries oxygen, carbon dioxide, nutrients, hormones, and waste products.

Blood

is a muscular organ that pumps blood throughout the body in most animals.

heart

Heart is enclosed by a double-walled sac known as the

pericardium

How many camber ?

4 chamber 2 upper 2 downward

The pericardium has two main layers

Fibrous pericardium Serous Pericardium

The outer layer, which is tough and provides protection and anchorage to the heart, preventing it from over- expanding.

Fibrosus pericardium

The inner layer, which consists of two parts

Serous pericardium

Serous pericardium consist of two parts what is it ?

Parietal Layer visceral layer

. Lines the fibrous

Parietal Layer

Covers the surface of the heart itself.

Visceral Layer (Epicardium):

Between these two layers which is parietal and visceral layer is the _____________? which contains a small amount of pericardial fluid

pericardial cavity

This fluid reduces friction as the heart beats, allowing for smooth movement within the pericardial

pericardial fluid

: Receives deoxygenated blood from the body

Right Atrium

: Pumps deoxygenated blood to the lungs for oxygenation.

Right Ventricle

: Receives oxygenated blood from the lungs.

Left Atrium

Pumps oxygenated blood to the rest of the body

Left Ventricle:

collects deoxygenated blood from the upper half of the body, including the head, neck, arms, and upper chest

SUPERIOR VENA CAVA

is the largest vein in the body

is a large vein in the body that carries deoxygenated blood from the lower half of the body back to the heart. It is one of the two main veins that return blood to the heart. ON

INFERIOR VENA CAVA The inferior vena cava

is a vital blood vessel that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. It is the only artery in the body that carries deoxygenated blood, which is in contrast to most arteries that carry oxygen-rich blood.

PULMONARY ARTERY

are responsible for carrying oxygenated blood from the lungs back to the left atrium. Oxygenated blood is returned from the lungs after it has undergone gas exchange, where oxygen is absorbed and carbon dioxide is expelled.

pulmonary veins

is the largest artery in the body, responsible for carrying oxygenated blood from the left ventricle to the rest of the body

aorta

It is a muscular wall that separates the heart's right and left sides, allowing the heart to pump blood efficiently

septum

: This separates the left and right atria (upper chambers of the heart).

Interatrial Septum

This separates the left and right ventricles (lower chambers of the heart).

Interventricular Septum

ensures that oxygen-rich blood from the lungs does not mix with oxygen-poor blood from the body.

septum

Between the right atrium and the right ventricle. It allows blood to flow from the right atrium to the right ventricle during diastole (when the heart is relaxed) and prevents backflow of blood into the atrium during systole.

Tricuspid Valve

Between the right ventricle and the pulmonary artery

pulmonary valve

Between these two layers which is parietal and visceral layer is the _____________? which contains a small amount of pericardial fluid

pericardial cavity
