What are the four core principles related to homeostasis?
Four core principles (1) feedback loops, (2) the relationship of structure and function, (3) gradients, and (4) cell-cell communication.
What is a vertical section through the body?
What is a vertical section through the body, dividing it into left and right? sagittal.
What best summarizes the principle of complementarity of structure and function?
1. The principle of complementarity of structure and function states that function is dependent on structure, and that the form of a structure relates to its function.
Which life process generates the raw materials and energy?
Metabolism
What is the definition of metabolism quizlet?
Metabolism refers to the chemical reactions in the body that build and breakdown molecules. Describe an example of metabolism. Cells need energy to function. If a person is eating something that has sugar, the sugar molecules get broken down into simpler molecules and that releases energy.
Which organ systems function as control systems?
Endocrine and nervous systems are the major control systems in higher animals. The nervous system depends on sensors in the skin or sensory organs to receive stimuli and transmit a message to the spinal cord or brain.
How is metabolism related to the nutrients in food?
Put simply, metabolism is a set of chemical reactions that take place in our cells. Our metabolism converts the food we eat into the energy we need for every action we do.
What are the five metabolic processes?
In humans, the most important metabolic pathways are: glycolysis – glucose oxidation in order to obtain ATP. citric acid cycle (Krebs’ cycle) – acetyl-CoA oxidation in order to obtain GTP and valuable intermediates. oxidative phosphorylation – disposal of the electrons released by glycolysis and citric acid cycle.
Which example best illustrates the principle of complementarity?
Which example best illustrates the principle of complementarity? Convolutions of the small intestines provides greater surface area for nutrient absorption.
Why are directional terms so important?
Why are directional terms so important? Because they allow us to explain where one body structure is in relation to another. Directional terms allow us to explain where one body structure is in relation to another. The breastbone is ventral to the spine.
What are the directional terms in anatomy?
Directional Terms Inferior or caudal – away from the head; lower (example, the foot is part of the inferior extremity). Anterior or ventral – front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body).
Is the thumb medial to the pinky?
The pinky is medial to the thumb. The thigh joins to the lateral border of the pelvis. The thumb is lateral to the pinky.
Is the wrist proximal or distal to the shoulder?
In medicine, it refers to parts of the body further away from the center. For example, the hand is distal to the shoulder. The thumb is distal to the wrist. Distal is the opposite of proximal.
What is the relationship between the elbow and the wrist?
The elbow is proximal to the wrist. Distal means farther away and proximal means closer to.
Are fingers proximal or distal to elbow?
Proximal then refers to something closer to the torso while distal refers to parts and places away from the torso. So a finger is distal to the wrist, which is distal to the elbow, which is distal to the shoulder.
