Explanation:

Summary and Review Answers:

1. The three basic planes of reference are the

• Sagittal (or median), frontal (or coronal), and transverse (or horizontal) planes. These are fundamental anatomical planes used to describe the orientation and location of body structures.

1. The dorsal cavity is subdivided into the

• Cranial cavity (houses the brain) and spinal (vertebral) cavity (houses the spinal cord).

1. The ventral cavity is subdivided into the

• Thoracic cavity (contains heart, lungs, etc.) and abdominopelvic cavity (divided into abdominal and pelvic regions, containing digestive organs, reproductive organs, etc.).

1. Define an organ

• A group of different tissues (epithelial, connective, muscle, nervous) that work together to perform a specific function (e.g., the heart pumps blood, the liver filters toxins).

1. Define an organ system

• A group of organs that collaborate to carry out a broad physiological function for the body (e.g., the cardiovascular system transports blood; the digestive system processes food).

Table Completion (Inference, as values are partially filled):

Table 1-2 (At Rest vs. After Exercise)

• Temperature: At rest (e.g., ~37°C), after exercise it typically increases (due to metabolic heat). Difference = After Exercise – At Rest (positive, as temperature rises).
• Pulse rate: At rest (e.g., 60–100 bpm; here, “15/10scc” likely a typo, maybe “15 beats/10 seconds” = 90 bpm). After exercise, pulse rate increases. Difference = After – At Rest (positive).
• Respiration rate: At rest (e.g., 12–20 breaths/min; here, “13”). After exercise, respiration rate increases. Difference = After – At Rest (positive).

Table 1-3 (Recovery Period)

• Time Finished Exercise: When exercise stops (e.g., 0 minutes for start of recovery).
• Time Returned to Normal: Time taken for temperature, pulse, and respiration to return to resting levels (varies by fitness, exercise intensity).
• Difference (Recovery Period): Time Returned to Normal – Time Finished Exercise (duration of recovery).

(Note: The handwritten “0” in Table 1-3 likely indicates “time 0” when exercise ends, and the recovery time is measured from there.)
