Which is located inside the lung Brainly?
Answer: The alveoli is in the lungs.
Is the alveoli in the lungs?
Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
What is the waste material liquid that is formed in the kidneys?
Urine is the waste-containing fluid that remains in the nephrons. The waste products are dissolved in urine, which is 95 percent water. Urine is carried from the kidneys to the urinary bladder through ureters, a pair of tubes.
What happens to the air which enters the nose?
Air enters the respiratory system through the nose. As the air passes through the nasal cavity, mucus and hairs trap any particles in the air. The air is also warmed and moistened so it won’t harm delicate tissues of the lungs. … Mucus in the bronchi traps any remaining particles in air.
Does air pass through sinuses?
When air enters the sinuses from the nasal cavities, mucus formed by the muscosae drains into the nasal cavities. The pharynx, or throat, is shaped like a funnel. During respiration, it conducts air between the larynx and trachea (or “windpipe”) and the nasal and the oral cavities.
What is the main function of the mouth in the respiratory system?
The mouth, also known as the oral cavity, is the secondary external opening for the respiratory tract. Most normal breathing takes place through the nasal cavity, but the oral cavity can be used to supplement or replace the nasal cavity’s functions when needed.
Which is the pathway of oxygen to the lungs?
When you inhale through your nose or mouth, air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung.
What is the difference between larynx and pharynx?
The main difference between pharynx and larynx is that pharynx is a part of an alimentary canal, which extends from the nasal cavity and mouth to the larynx and the esophagus whereas larynx is the upper portion of the trachea. … The larynx is also called the vocal box since it contains vocal cords.
What is the pathway of air into the lungs?
Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
What is another name for windpipe?
The airway that leads from the larynx (voice box) to the bronchi (large airways that lead to the lungs). Also called trachea.
Is also called windpipe?
Your trachea, or windpipe, is one part of your airway system. Airways are pipes that carry oxygen-rich air to your lungs.
How many alveoli do humans have?
In six adult human lungs, the mean alveolar number was 480 million (range: 274-790 million; coefficient of variation: 37%). Alveolar number was closely related to total lung volume, with larger lungs having considerably more alveoli.
What organ are in the upper respiratory tract?
The major passages and structures of the upper respiratory tract include the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx). The respiratory system is lined with a mucous membrane that secretes mucus.
Why does food not go into lungs?
A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow.

How will you describe the sequence of oxygen carbon dioxide and blood flow in your own words?
Answer: Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. … Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.
What is windpipe in human body?
The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people. The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum). The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung.
How are nose and mouth connected?
Behind your nose, in the middle of your face, is a space called the nasal cavity. It connects with the back of the throat. The nasal cavity is separated from the inside of your mouth by the palate (roof of your mouth).

- W – controlling WATER balance.
- E – maintaining ELECTROLYTE balance.
- T – removing TOXINS and waste products from the body.
- B – controlling BLOOD PRESSURE.
- E – producing the hormone ERYTHROPOIETIN.

What is the functional unit of kidney called?
The functional unit of the kidney is called the nephron. It comprises of a coiled renal tubule and a vascular network of peritubular capillaries. The tubule consists of different regions, each with their own important function.
How do kidneys eliminate waste?
Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder. Your bladder stores urine.
