Biology grade 11 respiratory system

Respiratory epithelium can secrete a variety of molecules that aid in the defense of the lungs. Respiration in fish and other aquatic organisms have special organs called gills, which help them in respiration. Which part of the digestive system produces basic solution, enzymes and insulin.

What keeps blood going in one direction to the heart in a vein. Equity and Inclusive Education The Virtual High School equity and inclusive education strategy focuses on respecting diversity, promoting inclusive education, and identifying and eliminating discriminatory biases, systemic barriers, and power dynamics that limit the ability of students to learn, grow, and contribute to society.

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.

Thus the rib cage's transverse diameter can be increased in the same way as the antero-posterior diameter is increase by the so-called pump handle movement shown in Fig.

In some SHSM programs, courses at Virtual High School can be bundled with other courses to provide the academic knowledge and skills important to particular economic sectors and required for success in the workplace and postsecondary education, including apprenticeship training.

Question Facts What do the red blood cells in the capillary pass through the wall of the surrounding cells. The second goal is to engage students in practicing and promoting environmental stewardship in their community. Healthy Relationships Every student is entitled to learn in a safe, caring environment, free from violence and harassment.

Which part of the small intestine is the shortest.

Secondly, the diameters of the alveoli increase and decrease during the breathing cycle. This ensures that the student will have opportunities to acquire the knowledge, skills, perspectives and practices needed to become an environmentally literate citizen. The trachea extends further down into the breastbone and splits into two bronchi, one for each lung.

Trachea — It is a long tube passing through the mid-thoracic cavity. Epiglottis — It is a flap-like structure that covers the glottis and prevents the entry of food into the windpipe. What is the name of the maximum amount of air that can be inhaled after a normal inspiration. Since surfactant floats on the watery surface, its molecules are more tightly packed together when the alveoli shrink during exhalation.

Many of the activities and tasks that students undertake in the Virtual High School courses involve the literacy skills relating to oral, written, and visual communication. As they gather information from a variety of sources, they need to be able to interpret what they are listening to, reading, or viewing; to look for instances of bias; and to determine why a source might express a particular bias.

All the pulmonary capillaries contain about ml blood.

At altitude this causes the pulmonary arterial pressure to rise resulting in a much more even distribution of blood flow to the lungs than occurs at sea level. This entirely passive bulging and shrinking during exhalation of the abdomen during normal breathing is sometimes referred to as "abdominal breathing", although it is, in fact, "diaphragmatic breathing", which is not visible on the outside of the body.

In other words, at the same arterial partial pressure of O2, a person with a high hematocrit carries more oxygen per liter of blood than a person with a lower hematocrit does.

Temperature control Panting in dogs, cats, birds and some other animals provides a means of reducing body temperature, by evaporating saliva in the mouth instead of evaporating sweat on the skin. Students who are taught these skills become critical thinkers who can move beyond superficial conclusions to a deeper understanding of the issues they are examining.

This not only drastically decreases the size of the rib cage, but also pushes the abdominal organs upwards against the diaphragm which consequently bulges deeply into the thorax Fig. Every organism, from an individual bacteria cell to a mighty blue whale, undergoes respiration.

But now, the abdominal muscles, instead of remaining relaxed as they do at restcontract forcibly pulling the lower edges of the rib cage downwards front and sides Fig. Healthy relationships are based on respect, caring, empathy, trust, and dignity, and thrive in an environment in which diversity is honoured and accepted.

It generates sound as air passes through the hollow in the middle. What is the name of the artery that supplies the head and neck with oxygenated blood.

Which blood vessel has the highest pressure. Which part of the body produces white blood cells. 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. Vocalization The movement of gas through the larynxpharynx and mouth allows humans to speakor phonate.

This is an upwardly domed sheet of muscle that separates the thoracic cavity from the abdominal cavity.

Using accepted forms of documentation to acknowledge sources is a specific expectation within the inquiry and skill development strand for each course. The final percentage grade represents the quality of the student's overall achievement of the expectations for the course and reflects the corresponding level of achievement as described in the achievement chart for the discipline.

In response to low partial pressures of oxygen in the inhaled air these sensors reflexively cause the pulmonary arterioles to constrict. Everestor in a diving chamber or decompression chamber. The third goal stresses the importance of the education system providing leadership by implementing and promoting responsible environmental practices so that all stakeholders become dedicated to living more sustainably.

Chapter Respiratory System Chapter Circulatory System Chapter Blood and the Immune System  · The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants.

The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary The respiratory system is a group of organs that provide living things with oxygen from outside of the body and disposes of waste products such as carbon dioxide -main function is so ensure that oxygen is brought into the body and made available to each cell that needs it and carbon dioxide can 5/5(1).
