Page 2: The Brain and Eye Structure

This section details the anatomy and function of the brain and eye, crucial components in the body's sensory and control systems.

Definition: The cerebral cortex controls consciousness, intelligence, memory, and language.

Highlight: The eye's ability to focus on objects at different distances involves changes in lens shape through ciliary muscle action.

Example: Long-sightedness (hyperopia) occurs when the eye cannot focus on near objects and requires convex lenses for correction.

Vocabulary: Accommodation refers to the eye's ability to adjust its focus for objects at different distances.

Page 3: Temperature Regulation and Endocrine System

This page covers thermoregulation and introduces the endocrine system's role in maintaining homeostasis.

Definition: The endocrine system uses hormones as chemical messengers to regulate body functions.

Highlight: Body temperature regulation involves both behavioral and physiological responses.

Example: When too hot, blood vessels dilate (vasodilation) and sweating increases to cool the body.

Vocabulary: Vasodilation is the widening of blood vessels to increase blood flow near the skin's surface.

Water and Ion Balance

This section details how the body maintains water and ion balance through kidney function and hormonal control.

Example: ADH (Anti-Diuretic Hormone) controls water reabsorption in the kidneys through negative feedback.

Vocabulary:

  • ADH: Anti-Diuretic Hormone
  • Osmosis: Movement of water across cell membranes

Menstrual Cycle and Hormones

This section explains the menstrual cycle stages and the hormones involved in reproduction.

Definition: The menstrual cycle is controlled by various hormones including FSH, LH, estrogen, and progesterone.

Example: The cycle consists of four main stages, including menstruation, proliferation, ovulation, and maintenance.

Page 1: Introduction to Homeostasis and the Nervous System

This page introduces fundamental concepts of homeostasis and the nervous system's role in maintaining internal balance. The content explains how organisms respond to environmental changes through coordinated systems.

Definition: Homeostasis is the maintenance of optimal conditions for cellular processes through regulation of internal conditions.

Highlight: Negative feedback systems are crucial for maintaining homeostasis, involving receptors, coordination centers, and effectors.

Example: The regulation of temperature, CO2 levels, and blood sugar demonstrates homeostatic control.

Vocabulary: Synapses are gaps between neurons where neurotransmitters facilitate signal transmission.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

David K

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
