Animal System Interactions

Animal System Interactions 12A

By the end of this lesson, I'll be able to explain how my body systems work together to complete basic functions and homeostasis, and how systems respond to various stimuli.

​

Objectives

Review the following fifteen slides (selected from the Unit 9 Ultimate Study Slides).

Come up with an answer to the following questions: 1. Give an example of a body system interaction. 2. Why do multiple body systems work together? 3. How does this enable the body to respond to stimuli?

Match

Match the following scenarios with their outcomes on a hot day if your brain did not receive input that your body was starting to heat up.

• You would start to sweat

• You would start to overheat

• You would start to shiver

• You would not feel any effect at all

Your body regulates temperature effectively

Your body fails to cool down

Your body reacts to cold

No change in body temperature perception

• Your body regulates temperature effectively

• Your body fails to cool down

• Your body reacts to cold

• No change in body temperature perception

Explanation Slide...

If your brain doesn't receive signals that your body is heating up, it won't trigger cooling mechanisms like sweating. This can lead to overheating, as your body can't regulate its temperature effectively.

Hotspot

Crotisol is produced at certain times of the day, as shown in the graph. Cortisol has a positive feedback on Process A, which outputs substance Z. At what time of day will the concentration of Substance Z be at it highest if there is no other feedback on Substance Z?

Drag and Drop

Select a relationship that is similar to the following relationship. Neuron:

Cardiac cell: Muscle cell

Muscle cell: Contraction

Circulatory system: Blood cell

Homeostasis: Endocrine system

Explanation Slide...

The relationship 'Neuron: Send electrical signal' shows a cell type performing a specific function. Similarly, 'Muscle cell: Contraction' illustrates a muscle cell executing its primary function, making it the correct choice.

Match

Match the following

• Composed of more than one cell

• The body system that processes food and turns it into energy for the organism

• Composed of several organs working together to perform a specific function

• The basic structural unit of all living organisms

• A single, self-contained entity that performs all the basic functions of life

Explanation Slide...

The function of an organ refers to its intended purpose, while the structure describes its physical arrangement. Therefore, 'function' and 'structure' are the correct terms to fill in the blanks.

Homeostasis is the

of a relatively constant environment.

Explanation Slide...

Homeostasis refers to the maintenance of a relatively constant environment within an organism, ensuring stability despite external changes. This is crucial for optimal functioning, making the correct choice 'Maintenance of a relatively constant environment'.

Drag and Drop

During strenuous exercise, body temperature increases. The body responds to the increase in temperature by sweating, which helps to reduce the body temperature. This situation demonstrates

synthesis

Explanation Slide...

This situation demonstrates homeostasis, as the body regulates its internal temperature through sweating to maintain a stable environment despite the increase in temperature during strenuous exercise.

Match

Match the following functions with the correct system:

• Filtering waste from the blood

• Producing hormones

• Transporting nutrients and oxygen to cells

• Breaking down food

• Circulatory system

• Digestive system

Explanation Slide...

The circulatory system's primary function is transporting nutrients and oxygen to cells, which is essential for cellular metabolism and overall body function. The other options are functions of different systems.

To regulate body temperature

Explanation Slide...

The primary role of the endocrine system is to produce and secrete hormones, which are crucial for regulating various bodily functions, including metabolism, growth, and mood.
