Biology grade 11 respiratory system

It generates sound as air passes through the hollow in the middle. Since making financial decisions has become an increasingly complex task in the modern world, students need to have knowledge in various areas and a wide range of skills in order to make informed decisions about financial matters.

The surface tension of a watery surface the water-air interface tends to make that surface shrink. Features of the human respiratory system The energy is generated by the breakdown of glucose molecules in all living cells of the human body.

Oxygen passes into the blood and carbon dioxide passes out of the blood Oxygen passes out of the blood and carbon dioxide passes into the blood Oxygen and carbon dioxide pass into the blood 7 What happens when we inhale breathe in. The enlargement of the thoracic cavity's vertical dimension by the contraction of the diaphragm, and its two horizontal dimensions by the lifting of the front and sides of the ribs, causes the intrathoracic pressure to fall.

In addition to a more forceful and extensive contraction of the diaphragm, the intercostal muscles are aided by the accessory muscles of inhalation to exaggerate the movement of the ribs upwards, causing a greater expansion of the rib cage. Which part of the body produces white blood cells.

They are able to engage in an inquiry process in which they explore complex and multifaceted issues, and questions for which there may be no clear-cut answers. The more acute the curvature of the water-air interface the greater the tendency for the alveolus to collapse.

The converse happens when the carbon dioxide tension falls, or, again to a lesser extent, the oxygen tension rises: The driving pressure forcing air into the lungs during inhalation is therefore halved at this altitude.

Respiratory System

Do veins have high or low pressure. What keeps blood going in one direction to the heart in a vein.

Every student is supported and inspired to succeed in a culture of high expectations for learning. What is the name of the blood vessel that has a large diameter, is short, and carries deoxygenated blood from the upper half of the body to the heart's right atrium.

Do veins or arteries have valves made of tissue. Using accepted forms of documentation to acknowledge sources is a specific expectation within the inquiry and skill development strand for each course. There are a number of technical and learning aids that can assist in meeting the needs of exceptional students as set out in their Individual Education Plan.
