What Is The Structural And Functional Unit Of Lungs?

What is structural and functional unit of liver?

Hepatic lobules are the minute, thin, profusely branched septa like trabeculae which extend inwards from the Glisson’s capsule and divide each liver lobe into polyhedral units.

These are the structural and functional units of liver.

So, the correct answer is ‘Hepatic lobules’..

What is structural unit of lungs?

Lung tissue consists mainly of alveoli (Figure 16.2. 6). These tiny air sacs are the functional units of the lungs where gas exchange takes place. The two lungs may contain as many as 700 million alveoli, providing a huge total surface area for gas exchange to take place.

What is the structural and functional unit of kidney?

The nephron is the functional unit of the kidney. The glomerulus and convoluted tubules of the nephron are located in the cortex of the kidney, while the collecting ducts are located in the pyramids of the kidney’s medulla. … The renal tubule is a long, convoluted structure that emerges from the glomerulus.

What is the functional unit of lungs?

The alveoli are the functional units of the lungs and they form the site of gaseous exchange.

What is the functional unit of brain?

Neurons. The basic functional unit of the brain is the neuron. Its functional role is to send and receive the electrical impulses that communicate messages about sensory, motor, and cognitive events throughout the brain.

What is the main function of the left lung?

The lungs’ main function is to help oxygen from the air we breathe enter the red cells in the blood. Red blood cells then carry oxygen around the body to be used in the cells found in our body. The lungs also help the body to get rid of CO2 gas when we breathe out.

What are the 7 functions of the kidney?

KIDNEYSRegulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.Regulation of osmolarity. … Regulation of ion concentrations. … Regulation of pH. … Excretion of wastes and toxins. … Production of hormones.

What is the basic structural and functional unit of the human body?

Cells. Cells are the basic structural and functional unit of all life. Examples include red blood cells and nerve cells.

What is the name of functional unit?

Answer. Explanation: Cells are called the structural and functional unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells.

What are the structural and functional unit of life?

The cell is the basic structural and functional unit of life. Cells are independent, single-celled organisms that take in nutrients, excrete wastes, detect and respond to their environment, move, breathe, grow, and reproduce.

What function do lungs perform?

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood.

Which lung is more important?

The right lung is shorter than the left lung to make room for the liver. The left lung is narrower than the right to make room for the heart. Lungs are sacks of tissue located just below the rib cage and above the diaphragm. They are an important part of the respiratory system and waste management for the body.

Why are there two types of nephrons?

There are two types of nephrons: Superficial cortical nephrons, which have their glomeruli in the outer cortex. They have shorter loops of Henle, which dip only into the outer medulla. … They have larger glomeruli, and thus have higher glomerular filtration rates (GFR).

What is the structural unit of an organism?

A Basic Structural Unit (BSU) is essentially a building block. In anatomy, the basic structural unit of the body is the cell. All living organisms have cells, which start as the zygote — the single cell at the beginning of life, after a spermatazoon fertilizes an oocyte.

What is the structure and function of the lungs?

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
