What is the heart called?
heart and circulatory system: The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body’s tissues..
What are the main parts of the heart?
Heart Chambers, Valves, Vessels, Wall and Conduction System The heart is made up of four chambers. The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides.
What is below the heart in the human body?
Your heart is located behind your sternum and between your two lungs. The heart is located closer to the front of your chest, in front of your esophagus and spine. Below your heart is your diaphragm, stomach, and liver.
Which side of body is heart on?
The base of the heart is located along the body’s midline with the apex pointing toward the left side. Because the heart points to the left, about 2/3 of the heart’s mass is found on the left side of the body and the other 1/3 is on the right.
Which organ is known as Heart of heart?
Chambers of the Heart The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.
What are the 4 main functions of the heart?
The four main functions of the heart are:Pumping oxygenated blood to the other body parts.Pumping hormones and other vital substances to different parts of the body.Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.Maintaining blood pressure.
Why is the heart so important?
The heart is important because it pumps blood around your body, delivering oxygen and nutrients to your cells and removing waste products. The heart has four chambers: two upper chambers called the right and left atria (singular: atrium) and two lower chambers called the right and left ventricles.
What is heart what is its function and structure Class 10?
The primary function of the heart is to pump blood throughout the body. It supplies oxygen and nutrients to the tissues and removes carbon dioxide and wastes from the blood. It also helps to maintain adequate blood pressure throughout the body.
What is the function of the heart?
Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly. Your heart is a muscle, and its job is to pump blood throughout your circulatory system.
What are the 5 parts of the cardiovascular system?

What is the size of heart?
According to Gray’s Anatomy, the heart length, width, and thickness are 12 cm, 8.5 cm, and 6 cm, respectively. In addition, the mean weight of the heart is 280-340 g in males and 230-280 g in females.
What is a heart in simple definition?
Anatomical terminology. The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs.
How does a heart beat?
Your heart has a special electrical system called the cardiac conduction system. This system controls the rate and rhythm of the heartbeat. With each heartbeat, an electrical signal travels from the top of the heart to the bottom. As the signal travels, it causes the heart to contract and pump blood.

What is the basic structure and function of the heart?
The structure of the heart The heart is a large muscular pump and is divided into two halves – the right-hand side and the left-hand side. The right-hand side of the heart is responsible for pumping deoxygenated blood to the lungs. The left-hand side pumps oxygenated blood around the body.
What are the structures of the heart?
The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood. The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs.
What are the 3 layers of the heart?
Three layers of tissue form the heart wall. The outer layer of the heart wall is the epicardium, the middle layer is the myocardium, and the inner layer is the endocardium.
What are layers of heart?
The heart wall is comprised of three layers, the epicardium (outer), myocardium (middle), and endocardium (inner). These tissue layers are highly specialized and perform different functions.
