Respiratory System Gas Exchange Process Human Respiratory System Human Anatomy Chart Human Anatomy And Physiology

The alveoli consist of an epithelial layer and extracellular matrix surrounded by capillaries.

. Alveoli increase surface area for exchange of gases. The surfactant in the alveoli is produced by Type II pneumocytes. During the process of inhalation as soon as the air enters the nose the hair and mucus present in the nose filter the air remove coarse particles.

All of the following statements about the respiratory system are correct EXCEPT. Vocal folds contain elastic fibers skeletal muscle and stratified squamous epithelium. Mucus present in the nose helps in moistening the air and the temperature of the nose is 37 degree C in human beings so the air becomes warm.

A i and iii c i and iv. If we were to examine cross-sections of the primary bronchi then secondary then tertiary and finally the respiratory bronchioles we would notice _____. C The alveolar epithelium is several cells thick.

Each alveolus is surrounded by a web of blood capillaries supplied by the _____. Trachea also called the windpipe is a cartilaginous tube that connects the pharynx and larynx to the lungs. Which of the following is not a characteristic of alveoli.

A person would be more likely to aspirate food into the right lung than the left lung because the right primary bronchus is. Most of the inside surface of alveoli is lined with Type I pneumocytes. Alveoli are surrounded by which of the following.

The alveoli are surrounded by tiny blood vessels called capillaries. Each alveoli has a network of capillaries that carry oxygen-poor red blood cells. The surfactant lining of the aveoli is produced by Type II pneumocytes.

Which of the following is the term for the lungs resistance to expansion. DAlveoli are the site of gas exchange in the lungseThe wall of the alveoli is composed primarily of. Nose and mouth.

These rings keep the respiratory passage open. D The alveoli are coated with surfactant. Diffusion - Process by which the alveoli remove carbon dioxide gas from the body and supply new oxygen to the blood 3.

Alveoli have a large surface area. In some alveolar walls there are pores between alveoli called Pores of Kohn. The elastic fibers allow the alveoli to stretch as they are filled with air during inhalation.

The alveoli of the lungs are surrounded by elastic connective tissue which contributes to normal exhalation. I are present in the chest cavityThis cavity is surrounded by ii on the sides which form a cage like structureA large muscular sheet called iii forms the floor or the chest cavity. Alveoli are not surrounded by blood capillaries.

E The alveoli are surrounded by capillaries. It is the alveoli that receive the oxygen and pass it on to the blood. The alveoli allow this gas exchange to occur.

Small surface area. The alveoli contain some collagen and elastic fibres. Is surrounded by C.

Surrounded by rich network of blood capillaries. A The alveoli are structures located at the tips of the bronchioles of the lung. Read the given passage and select the correct option for i ii and iii.

Which one of the following is surrounded by a rich amount of capillaries. During exchange of gases oxygen enters blood capillaries from alveolar air. As you descend from the trachea to the alveoli the amount of cartilage surrounding the passageway.

Alveoli and capillaries both have very thin walls which allow the oxygen to pass. The capillaries bring the red blood cells very close to the air space in the alveoli. Nostril is either of the two external.

Which of the following is not a characteristic of alveolia They shuttle air to and from the lungs b They maintain the shape and surface tension of the air sac cThey are arranged in clusters dThey sit at the end of the respiratory tree. Which of the following statements isare correct. Clara cells are found only in the bronchiolar epithelium.

Alveoli - Tiny air sacs in the lungs surrounded by blood vessels and membranes where gasses are exchanged. The primary function of the lung is gas exchange. Small surface area.

Haemoglobin has greater affinity for carbon dioxide than oxygen. CThe walls of the alveoli are very thin and are surrounded by a network of capillaries so that air and blood are separated by only a very thin respiratory membrane. True The bronchioles do not have smooth muscle in their walls only epithelium.

The correct option is B. False The alveoli are made of simple squamous epithelium. Asbestosis- An emphysema-like condition characterized by a shortness of breath 4.

Gas transport is the process of carrying gases from the alveoli to the systemic tissues and vice versa. The left lung has. The air in the alveoli is oxygen rich.
