Organs Of The Bodies

A system of organs and tissues, including
the heart, blood, blood vessels, lymph,
lymphatic vessels, and lymph glands,
involved in circulating blood and lymph
through the body.
fist-sized, muscular organ that pumps
blood through the body
 It is a smooth straight muscle.
The Pulmonary!
It’s responsible for
pumping the blood to
every cell in the body.
It is also responsible for
pumping blood to the
lungs, where the blood
gives up carbon
dioxide and takes on
The Systemic!
The blood leaves the
heart through the
aorta, goes to all the
organs of the body
through the systemic
 Then returns to the
heart through the
systemic veins.
There are three types of
vessels arteries, veins, and
Arteries-a blood vessel that
conveys blood from the
heart to any part of the
veins-tubes conveying
blood from various parts of
the body to the heart.
Capillaries-smallest of
blood vessels. They serve to
distribute oxygenated
blood from arteries to the
tissues of the body.
Also to feed deoxygenated
blood from the tissues back
into the veins.

such as rheumatic fever, that causes the

that results in narrowing of the coronary
arteries. This is caused by fatty deposits,
most notably cholesterol, on the interior
walls of the coronary arteries.

Endocrine System!
The system of glands that produce
endocrine secretions that help to control
bodily metabolic activity.
Functions of the system!
Endocrine system is a collection of
'glands' that produce hormones. These
hormones are very important for
regulating metabolism process, growth
of the body and sexual development.
 The glands release the hormones into the
blood stream and are transported to the
various cells and body parts. When the
hormones reach the target site, they
bind to the receptor cells with a lock and
key mechanism.
Problems that may occur!
Diabetes, Growth Disorders,
Osteoporosis, Polycystic Ovary
Syndrome, and also Thyroid Disorders.
consists of a collection of small glands
that regulates a number of vital functions
of our body.
 There are six major glands that form the
endocrine system in the human body.
They are the hypothalamus, pituitary,
adrenal, thyroid, pineal and
reproductive glands or gonads
It’s integral part of the substance of the
 A small cone-shaped structure, it
projects downward, ending in the
pituitary (infundibular) stalk, a tubular
connection to the pituitary gland.
The main endocrine gland. It is a small
structure in the head and is called the
master gland because it produces
hormones that control other glands and
many body functions including growth.
The pituitary consists of the anterior and
posterior pituitary.
One of a pair of small glands, each of
which sits on top of one of the kidneys.
