Which organs occupy the thoracic cavity

The five requirements of organisms provided by the external environment are water, food, oxygen, heat, and pressure. Additionally, why is it difficult to separate anatomy and physiology? It is difficult to separate anatomy from physiology because the structures of the body parts are so closely related to their functions; put another way, function follows form.

Living things obtain energy from their environment and use that energy to grow, develop, and reproduce. All organisms require energy to build the substances that make up their cells. The total sum of all chemical reactions in the body — the balance of anabolism and catabolism — is called metabolism.

Cellular metabolism is the process of breakdown of nutrients to produce energy. This process includes various chemical reactions that are taking place in the cell. What are the 11 major organ systems? Although each of your 11 organ systems has a unique function, each organ system also depends, directly or indirectly, on all the others. What are the characteristics of life anatomy? Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution.

What are the cavities of the head? The cavities of the head are cranial, oral, nasal, orbital, and middle ear cavity. The cranial cavity containing the brain. Teeth and tongue are housed in the oral cavity.

The nasal cavity includes sinuses which are filled with air. How is each adapted to the function of the organ? What is the importance of rugae, surf The pressure gradient is regulated by the dilation or contraction of the arterioles. After traveling through the afferent arteriole the now filtered blood en Cardiovascular System: Observe the diagram showing the major structures of the cardiovascular circulatory system.

What factors probably stimulated an early interest in the human body? Injuries, illness, aches, pains, bleeding, broken bones, devolped diseases, and contracted infections.

How did human health change as lifestyle changed? Malnutrition as people became sedentary. What types of activities helped promote the development of modern medical science? Experimentation, studying the human body, developing terms for the body, and Dissection of dead bodies. What are the differences between anatomy and physiology? Anatomy examines the structures of the body. Physiology considers the functions of body parts.

Why is it difficult to separate the topics of anatomy and physiology? It houses the organs of the upper central nervous system, including the brain and the spinal cord. The meninges is a multi-layered membrane within the dorsal cavity that envelops and protects the brain and spinal cord. The cranial cavity is the anterior portion of the dorsal cavity consisting of the space inside the skull. This cavity contains the brain, the meninges of the brain, and cerebrospinal fluid.

The vertebral cavity is the posterior portion of the dorsal cavity and contains the structures within the vertebral column. These include the spinal cord, the meninges of the spinal cord, and the fluid-filled spaces between them.

This is the most narrow of all body cavities, sometimes described as threadlike. The ventral cavity, the interior space in the front of the body, contains many different organ systems. The organs within the ventral cavity are also called viscera.

The ventral cavity has anterior and posterior portions divided by the diaphragm, a sheet of skeletal muscle found beneath the lungs. The thoracic cavity is the anterior ventral body cavity found within the rib cage in the torso. It houses the primary organs of the cardiovascular and respiratory systems, such as the heart and lungs, but also includes organs from other systems, such as the esophagus and the thymus gland.
